Hi Rk Sethi
So far I know Matlab 2009 definitely works with Optisystem. I have also used Matlab 2014 with Optisystem and haven’t really noticed much difference, except for the fact that using newer version of Matlab gives you all the benefits you can get writing Matlab codes in a newer version, regardless of whether or not you want to use Optisystem with it.
It’s just as far what I have experienced.
